I'm in the fortunate position to have 6 Supermicro older VOD servers with the following config:
- Supermicro 3U case, 3xPSU
- Dual Xeon 3ghz P4 class cpu (5 years old.. havnt checked the exact type)
- 4GB Ram
- 3ware 9500-8 SATA controller
- 8 SATA SLOTS and a lot of free drives.
- 2GB FLASH Bootdrive
What I'm curious about is the RAID5 performance on these old beasts in HW mode vs. SW on Linux with the controller set in JBOD mode.
I'm thinking on using Centos 5.5 or Ubuntu or ZFS RaidZ on OpenSolaris.
Any tips or Recommendations?
